Are Heavy Metals a Root Cause of Heart Attacks?


Science is dynamic and constantly changing, so it is nice to see when new studies consistently reinforce evidence-based beliefs. I am currently referring to another study published August 2021, showing the link between heavy metals and cardiovascular disease.

This has been a topic that I have been passionate about for years. So much so that I dedicated an entire chapter to it in my book, The Paleo Cardiologist.

To reiterate previous information, the British Medical Journal published a study which concluded:

  • High levels of lead are linked to an 85% higher risk of coronary disease and 63% higher stroke risk.
  • High arsenic levels are linked to over 30% higher risk of cardiovascular disease.
  • High cadmium levels are associated with a 33% higher risk of cardiovascular disease.
  • A separate study has found a link between mercury exposure and heart disease.

How Do Heavy Metals Cause Heart Attacks?

Toxic heavy metals have no role in body function, therefore any exposure/accumulation of these materials will interfere with our body’s natural processes. This interference causes cellular dysfunction because toxic metals like lead, mercury, aluminum, arsenic and cadmium block nutrients like calcium, magnesium, and potassium (vital minerals for heart function).

Other proposed mechanisms of metal damage include:

  • Oxidative stress and inflammation
  • Smooth muscle dysfunction
  • Endothelial dysfunction
  • Immune dysfunction
  • Mitochondrial dysfunction
  • Dyslipidemia
  • Disorders of coagulation
  • Autonomic dysfunction
  • Lower glutathione
  • Activation of Renin-Angiotensin system
  • Lower nitric oxide
  • Lower heart rate variability

How to Avoid/Reduce Metal Exposure

Metals and other chemicals enter the body in a few different ways. We can ingest them by eating, drinking, and breathing. Toxic substances can also enter the body through your skin. Below are some options that will help reduce your exposure to toxic materials.

  • Avoid air pollution by moving to an area with low levels. You can also mitigate indoor air pollution with the use of an air filtration system.
  • Drink quality water that has been filtered to eliminate contaminants.
  • Eat organic Paleo food: vegetables, pasture-raised meats, and wild seafood such as anchovies, sardines, and wild salmon. Limit tuna and other large fish because of mercury level concerns.
  • Use quality cookware that does not leach dangerous metals into your food.
  • Avoid vaccines because many contain aluminum and/or mercury. Request the inserts from the doctor to make an informed choice.
  • Use organic skin and personal care products. Here’s what we recommend.

Detox Your Body from Heavy Metals

There is a high likelihood that you have been exposed to heavy metals throughout your life. If you are curious about this issue, we recommend getting tested to see what your levels are for sure.

Whether or not you test, keeping your detoxification pathways open is an integral part of eliminating toxins. Staying hydrated to flush out kidneys and promote daily bowel movements helps keep these pathways open.

We also recommend our Daily Defense. It helps fight against toxic metal exposure and works to increase the removal of metals and other toxins by supporting elimination pathways.
